Hi,

If you want to automatically generate journal entries for each week using a scheduled action, you can follow these general steps.Create a new scheduled action:

<?xml version="1.0" encoding="UTF-8"?>
<odoo>
    <data noupdate="1">
<record id="ir_cron_schedule_journal_entries" model="ir.cron">

            <field name="name">Planning: generate next recurring shifts</field>
            <field name="model_id" ref="model_id"/>
            <field name="state">code</field>
<field name="code">model._schedule_journal_entries()</field>
<field name="interval_type">weeks</field>
            <field name="numbercall">-1</field>
        </record>
    </data>
</odoo>

In your custom module or through the Odoo developer mode, create a Python function that generates the required journal entries:
from odoo import api, models, fields

class YourModel(models.Model):
    _name = 'your.model'

    @api.model
    def _schedule_journal_entries(self):
        # Your logic to generate journal entries based on a 1-week gap

Hope it helps
